Abstract:Traditional design patterns are difficult to predict in advance the collision problems between electrical pipelines and system pipelines such as water supply and drainage, HVAC, etc., which can easily lead to a series of problems such as rework, material waste, and project delays during the construction phase. Based on this, the article elaborates on the application characteristics of BIM technology, sorts out the collision detection process of building electrical pipelines based on BIM technology, and summarizes the application points of building electrical pipeline construction based on BIM technology based on actual engineering projects, in order to provide feasible references for improving the accuracy of building electrical pipeline collision detection and on-site construction level.
